Locks are an essential element in the security of any building or environment; there are different types, each with specific features and advantages. In this article, we will focus on some of the particularly common types of locks, with an emphasis on locks with triangular, square, Double Barb Camlock with 3 mm Pin, fiat key, hex, and screwdriver keys.
Triangle, square, or hex key locks offer a practical and reliable solution for access management in a variety of applications where a high degree of security is not required, benefiting simple access management. Compact design and ease of use make these locks the ideal choice for a wide range of settings: from electrical panels to meter boxes, from automation turrets to industrial machinery. Also in this category of “simple” quarter-turn locks we find screwdriver key locks, a simple and inexpensive solution for applications that do not require a high level of security. The screwdriver key allows the lock to be easily opened and closed, making it ideal for household cabinets, tool boxes and other items that do not contain valuables.
Double Barb Camlock with 3 mm Pin locks, also known as “3-pin finned locks“, are an ideal choice for those who want a practical solution with an intermediate level of protection. These locks are distinguished by their unique key, different from common triangular or square imprints, thus offering superior security without the need for more effective protective measures, and maintaining the versatility of quarter-turn locks. The same is true for the impression lock with a “FIAT” cross key. This type of closure is ideal for applications requiring high stress resistance and a medium level of safety, such as on-board tools, robots, assembly lines, electrical panels, carpentry artifacts and technical compartments.
In these special quarter-turn locks, the push-and-turn system prevents accidental opening of the lock due to vibrations, ensuring maximum security. Both Double Barb Camlock with 3 mm Pin and FIAT tool operated camlock are an excellent choice for those seeking a practical, versatile and secure solution for access management in applications requiring an intermediate level of protection.

Let’s look at the features and strengths of impression locks, whether with a triangle key, square key or other configurations, and where they can be applied. Triangular key locks, such as those used in Electric boxes, offer robust and reliable protection, ideal for industrial applications and exposed environments. Square key locks, such as those used for gas meters or technical cabinets, offer a versatile and adaptable solution, with options ranging from latch locks to double wing models for electrical panels. These locks, with their installation flexibility and durable materials, are ideal for a wide range of applications, let’s discover them!
Main features and strengths of impression locks
- Reliable under all circumstances. The rotor of triangular keyed universals is under spring, and to open the lock you must first press with the key and then rotate. This smart feature increases the level of reliability on vehicles or machinery whose vibrations or shocks could cause the lock to open unintentionally. Thanks to the compression system, it also improves tamper resistance.
- Suitable for even the harshest environments thanks to the technopolymer version. Triangle key locks are available in technopolymer, a tough and weather-resistant material, making them suitable for environmentally complicated applications. The OR ring-optional-provides dust and splash protection to IP65 standards, making the lock suitable for wet or dusty environments. Stainless steel versions, for example, are perfect for withstanding the weather and corrosion, ensuring safety even in harsh conditions.
- Flexible beyond belief. The 7mm square terminal ensures a high level of lever customization. Standard equipment includes a 43 mm internal Q7 cam and a fastening nut, while different types of cranked and hook cams, drawer-tool and accessories can be fitted upon request to meet any safety requirement.
- Adaptable to different housing holes and thicknesses. The SVAR03715 adapter allows the drilling jig to be varied, while the version with 74 mm extension and adjustable lever offers additional installation flexibility for particularly thick doors or hatches.
